Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8761278, here are decompositions:

41 + 8761237 = 8761278
101 + 8761177 = 8761278
109 + 8761169 = 8761278
137 + 8761141 = 8761278
139 + 8761139 = 8761278
179 + 8761099 = 8761278
199 + 8761079 = 8761278
241 + 8761037 = 8761278

Showing the first eight; more decompositions exist.
